Sarah, a software tester, is responsible for evaluating an AI-based recommendation system for an e-commerce platform. She's considering the use of virtual test environments to conduct comprehensive testing without impacting the production system.How do virtual test environments contribute to the safety and risk mitigation during AI model testing, as understood by Sarah?
They don't contribute to safety and risk mitigation.
They allow AI models to be tested in isolation, preventing adverse effects on production systems or real data.
They solely focus on scalability and variability in testing.
